Problems solved by technology

However, the discharge temperature of traditional air compressors is about 80-150°C, which is a low-quality heat source (generally <230°C), and the scale of the heat of compression is small, making it difficult to recover, store, and reuse the heat of compression

Description

technical field [0001] The invention belongs to the field of industrial compressed air systems, and in particular relates to a high-efficiency air compression device based on gas adsorption and desorption effects and a method thereof. Background technique [0002] As one of the three major power transmission media in industry, compressed air is widely used in modern industrial production. Compressed air is used inefficiently compared to electrical and hydraulic transmission media. At the same time, the energy consumption of compressed air is large, and the total energy consumption accounts for about 9% of the country's power generation. Under the environment of global warming, improving the utilization rate of energy consumption of compressors is one of the effective ways to achieve energy saving and emission reduction. Significance. [0003] At present, only about 50% of the electric energy converted into compressed air during the compression process of the air compressor...
